If you’ve sunk hundreds of hours into previous Borderlands games, you know picking the right Vault Hunter is half the battle. Every class comes with quirks that can make your run a chaotic joy or a frustrating slog, depending on how well their kit matches how you like to play. We’re breaking down everything you need to know about Borderlands 4 characters abilities, from their signature action skills to hidden passive perks that change how you approach every fight. Don’t worry, we’re not spoiling any story beats here—we’re just sticking to gameplay details that will help you pick your main before you boot up the game for the first time.
Core Borderlands 4 Characters Abilities and Signature Action Skills
All four confirmed Vault Hunters come with a unique signature action skill that forms the backbone of their kit, with distinct pros and cons for different playstyles. Riot’s signature ability is “Berserker Rage” – he drops all guns, uses reinforced gauntlets to deal 2x melee damage, gains 70% damage resistance, and heals 10% of max health for every kill he gets during the 12-second window. The biggest downside to his kit is that he can’t use ranged weapons during the rage state, so he’s a poor fit for players who prefer to hang back and snipe.
Lira’s “Phase Warp” lets her teleport through solid objects, leave a decoy that explodes when enemies get close, and mark targets for 30% increased damage from all sources for 8 seconds. Her base ability cooldown is 18 seconds, which is fairly short compared to other classes, but she has very little built-in self-sustain, so you’ll need to rely on gear or teammates to stay alive in tough fights. When you’re looking at passive trees, always prioritize perks that directly enhance your core Borderlands 4 characters abilities before you invest in generic stat buffs like increased gun damage.
Jax’s “Mech Deploy” calls in a 15-ton combat mech he can pilot for 20 seconds, armed with a rocket launcher and minigun, or he can send it to fight autonomously while he stays back to snipe. The biggest downside to his kit is the 90-second base cooldown for the mech, so you’ll only be able to use it a handful of times per mission unless you invest heavily in cooldown reduction. Zee’s “Tech Hijack” lets them take control of enemy drones, turrets, and even vehicle weapons for 15 seconds, turning the battlefield’s deadliest tools against their owners. Their ability is almost useless in empty, open areas with no tech to hijack, so you’ll need to adjust your playstyle to stick to areas with plenty of enemy tech to leverage.
Hidden Passive Perks That Change Ability Playstyles
Each character has three unique passive skill trees, and you can mix and match points across all three to customize their core ability almost beyond recognition. Riot’s Berserker tree has a passive that lets him throw enemy corpses as explosive projectiles during his rage, while his Tank tree lets him share his 70% damage resistance with all nearby teammates when his ability is active. His third Support tree even lets him throw health packs to teammates during rage, turning a purely offensive ability into a hybrid support tool.
Lira’s Decoy tree turns her teleport decoy into a healing orb that restores 20% of nearby teammates’ health when it explodes, while her Warp tree lets her teleport up to three times in a row before the ability goes on cooldown. Her third Damage tree extends the target mark duration to 15 seconds, making her one of the strongest support options for endgame boss fights. You don’t have to stick to one passive tree either – you can mix and match points across all three to build a character that fits your exact playstyle, no meta required. I tested a hybrid build for Zee that combined hijack duration and reload speed buffs, and I could clear entire wave defense missions without firing a single shot of my own, just turning enemy turrets against their crews.
Jax’s Mech Autonomy tree lets his mech stay active for 40 seconds when left to fight on its own, while his Explosive tree lets him detonate the mech early for a massive area-of-effect explosion that deals 10x damage to all nearby enemies. Zee’s Hijack tree lets them take control of human enemies for 10 seconds, while their Tech Buff tree gives them 50% faster reload speed and 30% increased gun damage for every hijacked tool they have active.
Best Ability Combinations for Solo and Co-op Play
The right ability combination will make even the hardest endgame content feel trivial, whether you’re playing alone or with three friends. If you’re playing with a group, talk to your teammates before you lock in your build to make sure your Borderlands 4 characters abilities complement each other instead of overlapping. For example, having two Riot players both specced for melee tanking is a waste, but pairing a tank Riot with a support Lira, burst damage Jax, and crowd control Zee will let you take on any content in the game without breaking a sweat.
These are three of the most versatile, beginner-friendly ability builds we’ve tested so far:
- Solo Riot build: Combine Berserker Rage with the “Life Steal Frenzy” and “Corpse Toss” passives to clear hordes of enemies without ever needing to stop for health pickups. Add a few points in the ranged damage passive to cover gaps when fighting flying enemies that stay out of melee range.
- Co-op support Lira build: Pair Phase Warp with the “Team Damage Mark” and “Decoy Heal” passives to boost your entire team’s damage output by 40% while keeping everyone topped up on health during boss fights. This build works even in random public lobbies, since it complements every other class’s kit.
- Hybrid Jax build for any playstyle: Split points between the mech autonomy and detonation passives to use your mech as a distraction for trash mobs, then detonate it for extra burst damage against boss weak points. Add a few points in cooldown reduction to cut the mech’s wait time down to 45 seconds.
For solo play, you’ll want to prioritize abilities that give you self-sustain, like Riot’s healing on kill or Zee’s hijacked turrets that draw aggro away from you. In co-op, it’s smarter to lean into your character’s niche instead of trying to cover every base. You can respec your ability points at any fast travel station for a small fee of in-game cash, so don’t stress if your first build doesn’t feel right after a few missions. I’ve swapped my Zee build at least 10 times already, depending on if I’m playing solo, running content with friends, or grinding endgame raids.
Common Ability Mistakes to Avoid With New Vault Hunters
Most new players make the same handful of mistakes when they first start testing abilities, and most of them can be avoided with a little advance planning. The first big mistake is maxing out your signature action skill first before investing in supporting passives. A level 1 action skill with strong supporting passives will always perform better than a maxed action skill with no passives to back it up, so spread your points out evenly between your core skill and its supporting perks.
The second common mistake is ignoring cooldown reduction stats on gear. You can get up to 40% cooldown reduction from gear alone, which cuts your ability wait time almost in half for constant access to your strongest tool. This is especially important for classes like Jax with long base cooldowns, or Lira players who rely on teleport to escape tight spots. I’ve seen players skip perfectly good gear just because it doesn’t have a gun damage buff, but cooldown reduction will give you far more value in 90% of fights.
The third mistake is not testing your ability in different scenarios before committing to a build. Just because a build works well in open world fights doesn’t mean it will hold up in close-quarters dungeon runs or long boss fights. For example, Riot’s melee-focused build is amazing for open world hordes, but it struggles against flying bosses that stay out of melee range, so you’ll want to have a backup build with ranged damage buffs for those fights. I made this mistake on my first playthrough, when I spent 20 levels building a pure melee Riot, only to hit a flying boss that I couldn’t reach at all, and I had to respec halfway through the fight to add ranged damage buffs.
The best part about Borderlands’ class system is that there’s no wrong way to play. You don’t have to follow meta builds if you’d rather run a silly build that lets you hijack every enemy vehicle on the map or run around punching everything in sight. Take time to test each of the Borderlands 4 characters abilities for a few missions, mix up your passives, and don’t be afraid to try something weird. You might stumble on a combination that works even better than any build you find online, and that’s half the fun of looter shooters. If you’re still stuck on which character to pick, try out each one for the first 30 minutes of the game before you commit – the opening mission lets you test every character’s core ability before you lock in your main.
